Reciprocating at the forward end of the ovcrhanging arm 'is a needle bar 4, carrying two needles 5 and 6. The needle bar is reciprocated by a needle-lever 7, which is connected to an eccentric Strap t3, cooperating with an eccentric on the main shaft 9.

The covering' threadl c is led through a. fixed guide l() and an oscillating hoor 11 engages this covering thread l: and lays the same in loop form so that it is stitched down by the needle threads. A looper of the ordi nary construction cooperates withthe needles beneath the work support, and carries the looper thread The material is held on. the work support by a presser 'foot 12, carried by a .presser bar 13, .which may be of the usual construction. Said presser foot is formed with a guiding slot 1st, which extends from the extreme forward end thereof rear* wardly in the line ot' feed. The presser toot has a needle opening 15 through which the needles pass.

rlhe machine includes a trimming' mech` anism having horizontally disposed trim .min blades. (lne of these blades is indicate at 15. This blade is stationary and is fixed to the presser 'foot 12. Cooperating with this fixed blade is a movable blade 1G. These blades are so disposed as to trim the uptiirned edges yof the Jtabric sections directed into the guiding slot li. rlhe collarette strip passing underneath the presser foot'has its edges turned up` so as to be brought into the range ot' this trimming mechanism. Afterwards they are brought back into theplane or' the iabric sections and stitched, as above noted` by the stitching mechanism, which includes the needles 5 and G., the cross thread laying mechanism and the looper cri-operating therewith.

rlhe body portion oi" 'the garment G passes underneath the presser' foot, and is guided by a lip 17, mounted ,on the throat plate 18 andeextending upwardly therefrom. This lip is curved to the lett slightly, as viewed in Figures 7 and d. and serves to direct or iiptiirn the edges ofthe collai'ette strip to bring them into the range of the trimming devices. rl`he body tabric'is preferably passed through the machine without trimming as the neck ot the garment is usually shaped ready 'for the attachment of the collarette strip thereto. The collarette strip S is directed to the stitching mechanism by guiding devices which include' a tubular guide 19, which is carried by a bracket 20, and the bracket 20 is in turn clamped to the work support 1 by means ot the clamping screw 21.. The tabular guide 19 is secured to the lower end of an arm E' which is pivoted at 23 to the bracket 20. The lower end of this arm is bent laterally, as indi- The pivoted connection between the arm and thebraclret is of such a character as to vertically holdthe `arm in adjusted position against either stop.

The material .is fed underneath the presser toot by a feeding mechanism which includes iteed dogs 28, which may be of theusual construction and operated by any suitable mechanism. These feed dogs are preferably given diiei'ential feeding movement. `rli`he feed dogs and the collarette strip and draw underneath the presser toot.

ll'hen the parts are positioned, as shown in tiill lines in Figures 1 and 2, the collarette strip passing underneath the presser foot will be directed so that `only a small portion ot the edges will be trimmed ottv and the line of trimming will loe substantially parallel with the edges ot' the strip. "When the guiding devices are positioned, as' shown in Figure 3. then the tubular guide is arranged relative to the stitching mechanism, so that the folded edge ot the collarette strip and not the tree edges will be substantially in line'ivit.i the trimming 'point,.so that while the machine is operated and the guide maimoperate both iiion the bodi fabric l it determined by these adjustable stops 26 and;

tained in this position the line of cutting steps will take place rbefore the collarette strip will pass directly to the trimming members trom the tubular guide 19. As a re. suit. the line of trimming will follow the strip leading from the tubular' curved line between a, and indicated in Figures 1.0 and 14.# of the drawings. -T he rea.v son for this is thought to be apparent. The operator shifts the guide by hand and at will, and it is the feed of the machine drawing the strip in underneath the presser foot,

with this new position of the guide` which causes the-tapering of the collarette strip.

in the beginning of the collarette stitcha operation, 'the guide 19 is set, as viewed 'passes underin Figures 5 and The stri heath the presser toot and t e line of cutting is parallel ".vilfh the, folded edge an@ close thereto, rlhe resulting fiction oi 'ine stitching mechanism and trimmer on e collarette strip is indicacil in Figur@ ll the drawings wherein if.: will noted hzita small portion oi: he @allai-etti sii-ip is passing' through the nacliine underneath and lijf the erui quickly desirs to .definey a movement wherein ihr guida is shifted fronti one extra nr posiiun in the other wihiiu stopping; 'as distinguifi from a step by step innvcni n which i neressariij' a consiifirrnhle period oi? inn/Q.
